Device Description

The IMICRYL family of silicone impression materials: includes the brand names SPIRIAS, NICETY, REFLECT and PE Sil. It is used by dentists to obtain anatomical data of the patient's mouth and then to obtain a useful plaster cast to diagnose problems, identify necessary interventions and/or check their effectiveness. They are elastomeric materials with hydrophilic properties, high tear strength, dimensional accuracy and resistance to permanent deformation, cured by addition reaction.
The IMICRYL family of silicone impression materials consists of six different viscosities (putty soft, heavy body, medium/monophase/regular body, light body, extra light body, bite registration) for various application systems. Putty Soft consists of 1:1 250 and 1:1 300 mL jars, other consistencies 1:1 50 mL syringes. Although the consistency and composition of medium, monophase and regular body products, which have type 2 consistency, are exactly the same, they are offered for sale under three different names.

AI/ML Overview

The provided text describes the acceptance criteria and performance of the IMICRYL Impression Materials device, specifically focusing on its physical properties and comparison to a predicate device. However, it does not describe an AI/ML-based medical device. Therefore, I cannot extract information related to ground truth establishment, expert adjudication, MRMC studies, or training/test set sizes for AI/ML models.

Based on the information provided, here's an attempt to answer your questions with the available data, clarifying where information is missing due to the nature of the device:

Device Type: Dental Impression Material (not an AI/ML device)
Study Purpose: To demonstrate substantial equivalence to a legally marketed predicate device (HySil Impression Materials, K170736) for FDA 510(k) clearance.


1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria are implied by the ISO 4823:2021 standard requirements and the comparison to the predicate device's performance. The "Remark" column in the provided table indicates where the new device's performance is considered "Same" or comparable, even if the exact numerical acceptance criteria aren't explicitly stated as pass/fail thresholds. The reported device performance is directly given in the "New Device" columns.

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

  • Sample Size for Test Set: The document refers to "in-vitro bench tests." The specific sample sizes for each physical test (e.g., how many samples were tested for consistency, dimensional change, etc.) are not specified in this summary document.
  • Data Provenance: The tests were conducted by the manufacturer, IMICRYL DIS MALZEMELERI SANAYI VE TICARET A.S., which is based in Turkey. These are laboratory bench tests, not patient data. The nature is prospective in the sense that the tests were performed specifically for this 510(k) submission on manufactured material samples.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This is not an AI/ML device, so there is no "ground truth" derived from expert consensus on medical images or clinical outcomes. The "ground truth" for the physical properties is established through standardized laboratory bench testing methods defined in ISO 4823:2021. The results are objective measurements (e.g., mm, %, sec, μm), not subjective interpretations requiring expert review.


4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

Not applicable. This is not an AI/ML device involving human interpretation review. Bench tests are objective measurements based on specified protocols.


5. Is a multi-reader multi-case (MRMC) comparative effectiveness study was done? If so, what was the effect size of how much human readers improve with AI vs without AI assistance?

Not applicable. This is a material testing for a dental impression material, not an AI/ML device designed to assist human readers. No MRMC study was performed.


6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

Not applicable. This is a physical material, not an algorithm.


7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

The "ground truth" for this device's performance is based on objective physical measurements conducted in a laboratory setting according to the ISO 4823:2021 standard (Dentistry-Elastomeric impression and bite registration materials). The measurements include consistency, working/mixing time, detail reproduction, dimensional change, elastic recovery, strain-in-compression, and hardness.


8. The sample size for the training set

Not applicable. This is not an AI/ML device. There is no concept of a "training set" for physical material properties.


9. How the ground truth for the training set was established

Not applicable. As this is not an AI/ML device, no "ground truth for a training set" was established. The "ground truth" (physical properties) is determined by direct laboratory measurement.

Dear Husamettin Sonmez:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal

{1}------------------------------------------------

statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
